Application mea Marelfieio'.' serial No. 551,359.

To all whom 'it may concern:

Be it known that I, WILLIAM C. GoLnlmm,M

a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented new and useful Improvements in Bracket-Lamps, of which the following is a specification.

The present invention relates to lamps,

and more particularly that type in which liquid fuel or illuminant is vaporized and mixed with air before burning.

The primary object is to provide a bracket structure of a simple, novel and effective character.

In the drawings :-Figure 1 is a side elevation of the lamp, with the globe and globe support illustrated in section. Fig. 2 is a detail sectional view on an enlarged scale through the vaporizer, air mixing means and burner.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment disclosed, a horizontal vaporizing tube 3 is employed, having at one end a suitable supporting shell 4, by means of which said tube can be mounted on a wall or other support. The other end of the tube is provided with a head 5, from which depends a vapor discharge nozzle 6. A valve casing 7, disposed in line with the tube, has rotatably mounted therein, a valve stem 8 that passes through a packing gland 9, andhas an exposed knurled head 10. This stem carries at its inner end a suitablevalve 11 Vthat operates against the direction of flow of vapor, and is movable into and out of coaction with a valve seat l2 that is thus interposed between the vaporizing tube and the nozzle.

A collar 13 is fitted upon the outer end portion of the vaporizing tube, and carries an upstanding stem 14 and a depending stem 15. The upstanding stem 14 supports a suitable bell 15a. Ahead 16 is provided with an outstanding iinger 17 having an opening 18, through which the stem 15 passes, and a set screw 19, threaded into the end of the linger 17, has its inner end engaging in a groove or socket 20 formed in the stem 15, so that the said head 16 is supported by the stem. This head has in its upper side, an opening 21 that detachably receives the nozzle 6, and it is furthermore provided with an outstanding tube extension 22 forming an air inlet.

The outer end of said tube extension supports an adjustable air regulating cap 23.

The head 16 furthermore carries a depend ing air and vapor conducting tube 24, that extends through the top and nearly to the bottom of an air and vapor mixing chamber.

25 carried by said tube. This chamber 25 is provided with one or more depending burners 26 having perforated caps 27, and constituting mantle supports.

In this structure, the liquid illuminant passing through the tube 3, will be vaporized by the heat from the burner, and will discharge through the nozzle 6, into the tube 24. Air will be entrained through the extension 22, and the air and vapor will consequently pass into the mixing chamber 25, from whence it will discharge at the burners 27, where it will be burned. The mantles supported from these burners, will consequently be made incandescent. The said mantles are preferably inclosed in a suitable globe 28 that is carried by a supporting ring or sleeve 29. This sleeve is mounted on the set screw 19 and the extension 22.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a lamp, the combination with a substantially horizontal vaporizing tube, of means located at one end for supporting the same, a depending nozzle carried by the other end, a substantially horizontal valve controlling the passage of vapor from the tube to the nozzle, and having a handle at one end of the tube, a straight air and vapor tube directly above the burner, and having In testimony whereof, I have hereiinto set depending and upstanding stems in line my hand, in the presence of two subscribing therewith, means carried by the upper end witnesses.

of the air and vapor conducting tube for de- VILLIAM C. COLEMAN. 5 tachably supporting the same from the de- Witnesses: Y

pending stein, and a bell mounted on the GEO. D. SHIELDS7 upstanding stern. D. S. COLEMAN.
